' Applcationled January 29, 1927. VSerial No. 164,555.`

Our' invention relatesV yparticularly to brushes for paint and varnish. Themain object isv to provide improvements on the brush of vPatent 1,277 ,508, dated September 3, 1918. In detail we have sought to simplify the construction and yet protect the parts from injury and from accidental operation.

Another object is to make it possible to apply more power for thepurpose of operating the prop or support.

According to our invention, we provide a prop or support independent of the bristles for supporting the brush in a standing position. This prop is normally housed within the body and handle of the brush and is adapted to be, when the brush is not in use, in a position where it will bear the weight of the brush without injuring the bristles.

The operating means for this prop or support consists of a gear mounted or housec entirely within'the body of the brush and provided with external crank arm by which it may befoperated.

In the accompanying drawing we have illustrated one form of the invention.

Fig. 1 is a side view of the brush construction embodying our invention, part ofthe bristles being broken away to disclose the tip of the prop and the inner operating mechanism being shown dotted.

F ig. 2 is a transverse sectional view of the construction. f'

. Fig. 3 is a side view, part of the handlev and bristles being broken away.

Fig. 4 is a fragmentary sectional view. The body 5 of the brush may be of any suitable material such as wood or metal, and

made up of one or more parts. Y

The handle 6 may be of any suitable construction and secured to the body lin any suitable manner.

The bristles 7 may be of any suitable type and secured or set in the body in any suitable mann'er. Usually and preferably, the

body and upper ends of the bristles will be enclosed and protected by means of a metal. shell or band 8 which may serve as a part' of the means of connection between the bristles 'and the body. y

The prop or support 9 is in the form of a rod or stem which may have any suitable form of lower end or ltip adapted to rest upon a support when in the projected position shown in Fig. 1.v This rod is movable lfarm on to it from either direction.
